If the internal junction temperature exceeds safe limits (typically around 150°C), the IC automatically disables the output stages. It re-enables once the temperature drops to a safe threshold.

Troubleshooting and Common Issues Mx1616 Motor Driver Datasheet
Ensure adequate copper pouring on the PCB ground plane. Large ground traces help dissipate heat away from the IC during sustained high-current operations. If the internal junction temperature exceeds safe limits

Here is a comprehensive datasheet and application guide.
The DRV8833 has similar performance but is generally more expensive. The MX1616 is often a more cost-effective alternative for budget projects. 7. Troubleshooting and Tips
